Faraday's law fails here. Let's go back to basics. We use the Lorentz force. And what is happening is as the rod rotates, the charges in it rotate too. However, the rod is neutral so there is no net ...

It is the displacement of the point on which the force is applied. This is it. That is the real definition, period. The books which do it otherwise are wrong. I would like you to read Resnick Halliday ...

Strictly according to Double Slit experiment calculations, yes infinite fringes are possible if (1) the slits are infinitesimal and placed infinitely apart, but actually, the fringes will be very ...

Your doubt is well found. It is actually the book which is wrong here in choice of words. Basically, according to the term "reaction", it should mean that the answer should be (3), but the book is ...

You can consider an object to be a point particle, when you only think of its translatory motion, means it is moving in 3-D like a point would, like, if a point particle moves around, it is so small ...

Charges at rest move when a force is applied on them and this is due to Newton's laws. Now to apply a force, we need a field, like electric/gravitational field. Each field acts upon certain ...

The shortest euclidean distance between three points namely 1,2,3 follows that $dist(1,3)=dist(1,2)+dist(2,3)$. where $dist(x,y)$ is the vector between points x and y. Now we from daily ...

It was found through the law of dynamics we calculated and observed the particle to follow on a macroscopic scale failed miserably when applied to microscopic objects. The particle showed some ...

Current is flow of charges - (1) Charges flow whenever there is an external $\vec E$ i.e. an $\vec E$ besides the charge's own field . So talking about electrostatic field $'\vec E$ $'$ which is ...
